15 Claims.

The present invention relates to industrial tables and more particularlyto supports for work boards, which, as a matter of example, are suitablefor use by furriers.

A use for the device concerned with herein, is where comparatively largeboards are used to have fur pelts nailed onto both surfaces thereof. Itusually requires two persons to lift such board onto trestles or othertable-top supports, turn such board over when required and thereafterremove it from such supports to make room for the next board to beworked on.

An object therefore of this invention is to provide a novel and improvedsupporting means for a board or the like, whereby it is convenient forone worker to lift the board onto or oil the trestles, or turn same overthereon.

A further object hereof is to provide a board supporting means of noveland improved construction, adaptable for boards of various area sizes.

Another object of the present invention is to provide a novel andimproved device which enables manipulating the work board as mentioned,and which-can be made as an attachment for existing trestle or othersupporting structures.

A further object hereof is to provide a novel and improved device of thecharacter described, which is simple in construction, reasonably cheapto manufacture, easy to use and efiicient in carrying out the purposesfor which it is designed.

Other objects and advantages will become apparent as this disclosureproceeds.

In the accompanying drawings forming part of this application, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 is an end view of a work board and a supporting means thereforembodying the teachings of this invention; said board being shown in amanually held position.

Fig. 2 is a section taken at line 2-2 in Fig. 1.

Fig. 3 is a section taken at line 33 in Fig. 2 with the table resting onthe supporting structure.

Fig. 4 is a-perspective view showing a bracket included in saidembodiment.

In the drawings, the numeral [5 indicates a work board and I6 anysuitable supporting means therefor, as for instance the pair of horsesI1 and 18 which are in spaced relation thereunder. Mounted underslung onthe respective top rails of said horses or trestles I! and I8, are thebrackets 19 and 20 respectively. Bracket l9 carries the tubular member2|, while bracket 20, carries rod member 22; said members 2| and 22being in telescopic relation. The numerals 23 and 24 are bolts forsecuring said telescopic members to the respective brackets, while 25 isa thumb screw to maintain said members in a definite relation. Thus fardescribed, is a telescopically adjustable table-top supportingstructure. At the remote ends of such structure are the respectivefoldable braces designated generally by the numerals 26 and 21. Brace 26comprises a link 25 pivotally mounted at one end at 28 to member 2| andanother link which may be of the extensible type as 26", pivotallymounted at one end to a board clamp 29 at; the other ends of said linksbeing in pivotal relation by pin 3|. Brace 21 is of identical structure.The links comprising same are identified by the numerals 27' and 21".Pivotal connections are 32, 33 and 34, while 35 is the associated boardclamp. The clamps 29 and 35, are comprised of the respectivechannel-pieces 29' and 35, and the respective thumb screws 29" and 35",to engage board l5.

For use, the horses I! and I3 are spaced apart as far as is practicaland bolts 23 and 24 tightened, as well as thumb screw 25, so that theclamps 29 and 35 are a proper distance apart to receive board l5 betweenthem. The extensible links 26" and 21" are adjusted by means of therespective set screws 36 and 31, so that the total length of the braces26 and 21 shall be identical when extended and suflicient to permit theboard i5 when mounted to be turned to clear the horses I! and It. Aboard l5 to be worked on, is then placed with its forward edge restingon the floor and a surface thereof resting against said horses, meaninga position'indicated by the numeral l5 in Fig. 1. The clamps 29 and 35are mounted substantially centrally onto the side edges of the board [5.The entire assembly being of sturdy construction, board I5 is taken holdof at its side edges near the floor in its position l5 and its lower endlifted, at the same time sliding said board along the top rail of saidhorses until it lies in position [5". To reverse the position of theboard so that what was its underside shall face uppermost, said board istaken in hand, its forward end is then lifted and pulled forward, andsaid board can thenbe turned about while its rear edge slides forwardatop the horses. All such manipulation of the board I5, can beaccomplished easily by only one person. Once the device is set up forthe largest size board; and if the widths of the boards used are not atgreat variance, the only adjustment which need be made is for length,requiring only adjustment of the telescopic brace members securedbythumb screw 25.

To aid initial lift of the board I5, a lever 33 may be provided,rotatably mounted on rod 22, intermediate the ends of said lever, anddimensioned so, that it is balanced so that it does not revolve ofitself when board I5 is off the trestles l1 and i8.

When the boards used are of uniform size as to their widths, theadjustability afforded by links 26" and 21" may be omitted, and if alsoof uniform length, the adjustability of spacing the horses, may beomitted.

This invention is capable of numerous forms and various applicationswithout departing from the essential features herein disclosed. It istherefore intended and desiredthat the embodiment shown herein be deemedillustrative and not restrictive and that the patent shall cover allpatentable novelty herein set forth; reference being had to the.following claims rather than to the specific description and showingherein to indicate'the scope of the invention.
